High Shear Emulsifier means that the material is in a vacuum state, and a high shear homogenizer is used to quickly and evenly distribute one phase or multiple phases to another continuous phase. Due to the high tangential speed generated by the high-speed rotation of the rotor and the strong kinetic energy brought by the high-frequency mechanical effect, the material is subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tearing and turbulence in the narrow gap between the stator and the rotor, forming a suspension (solid/liquid), emulsion (liquid/liquid) and foam (gas/liquid). The material is dispersed and emulsified evenly in an instant, and after high-frequency reciprocating cycles, a bubble-free, delicate and stable high-quality product is finally obtained.
